20L High Precision Rotary Evaporator with 120W Motor and 5L/h Evaporation Rate for Laboratory Applications
This high-precision 20L rotary evaporator is designed for concentration, crystallization, drying, separation, and solvent recovery applications in pharmaceutical, chemical, and biopharmaceutical industries. The compact motor design ensures efficient operation while maintaining safety and precision.
Under vacuum conditions, the rotating flask maintains constant temperature heating while rotating at controlled speeds. This creates a large surface area film on the flask wall, enabling efficient solvent evaporation. The vapor is then condensed by a high-efficiency glass condenser and collected for recovery.
- Laboratory reflux operations and rapid solvent evaporation
- Concentration of trace components and reaction processes requiring stirring
- Purification of biological products sensitive to high-temperature decomposition
- Digital speed and temperature display for easy visual operation
- PID temperature controller ensures precise thermal regulation
- One-way check valve automatically closes during receiving flask drainage
- All liquid-contact components made of borosilicate glass 3.3 and PTFE
- Specialized motor provides quiet, vibration-free precision operation
- Downward-condensing vacuum connection for safe vacuum operation
- Modular design with separate rotary and water bath modules for easy maintenance
- Explosion-proof motor ensures complete process safety
